Mortuary Response to VHF - 3 "Beginnings"

Before we continue with our preparation of proper Mortuary Response it is important as we move towards the decontamination and physical handling of victims and bodies, to understand the complexities of VHF transferrence to infection of Mortuary personnel.

Ebola Virus is just one (1) of the many viral hemorrhagic Fever Pathogens that some feel may have evolved into the environment possibly due to jungle deforestation. As plants check and balance many infectious compounds during growth through photosynthesis, the removal of the natural “balance” of the forest floor may have an impact on the mutation of viral infectious agents and their relative exposure towards man and animals. When the system is altered due to mankind’s interruption of this self-managing ecosystem the release of these agents may be possible.

Ebola is a filovirus which is enveloped, non-segmented, and a negative-stranded RNA virus. This result is a severe disease result with a high case fatality of 50% to 90% mortality amongst those exposed. While advances are constantly being made in medical research, in 2014 there was an absence of a specific treatment or protective vaccine.

From 1970 to present there have been greater than 20 previous Ebola and Marburg (Ebola type) virus outbreaks. The 2014 West Africa Ebola outbreak was caused by Zaire Ebolavirus, currently of which there are five (5) different types known? This is questionaries’ as these five derivatives are the current one’s known to medical research. Are there others unknown? Medical authority experience dictates there is a strong possibility of additional unknown types yet to be found.

Ebola like or VHF viruses are many times referred to as a Zoonotic virus, or one in which comes from animal contact. For this to spread a “host reservoir” is required. Host reservoirs are frequently animals included in the local population’s diet. Evidence suggests that bats may be one of the reservoir hosts for the Ebola virus. Bats that carry the virus can transmit it to Apes, antelope as well as others that may be in the local human food source. Additionally any bat in contact with humans is also capable of transmitting the disease to the local population.

Spillover from ingestion incidents occur from this contact. A Spill-Over event occurs when these animals or humans make contact with a reservoir host. Usually this occurs through the hunting and preparation of the animal meat for cooking and consumption.

Once the first human has been infected, human-to-human contact passes the virus from person to person by contact with blood or bodily fluids of the infected person.
